Question

The perimeter of a 6-sided figure is 72 units, and the length of each side is x+5. What is the value of x?

Answer 1

`x=7`

Explanation:

`72` divided by `6` sides (assuming the sides are of equal length) is `12` units per side. Because `x+5` is the length of each side you can plug in `12` to get

`x+5=12`

Solve to get `7`.
